3 Claims. (Cl. 299-24) The present invention relates generally tocontainers, and has particular reference to containers for vaporizablesolid material such. as paradichlorobenzene.

It is a general object of the invention to provide a container ofimproved structural character lized.

A more particular object is to [provide a container which is primarilyintended for generation of anti-moth vapors in closets or in garments orgarment enclosures; and which is specially suited larly-shaped blocks.

The container of the present invention is generally rectangulararrangement of the blocks to be accoimnodated therein. The embodimentillustrated in the drawings show this predetermination to be such thatfour blocks can be accommodated, arranged as shown in the drawings.

A feature of the invention resides in the provision of air circulationperforations only in one preferably in one or both of the side walls,wherethe container will encounter the flattened vaporizable blocksedgewise and bloc Another feature of the invention lies in forming atways visible therethrough.

Another feature of my invention is the pro- An unusually efficient,compact, inexpensive and sturdy construction results when both sidewalls are transparent and perforated and when each of these Walls isslidably mounted, as by forming opposed guide channels in the front andrear walls of the container. It is this preferred 2: embodiment of theinvention which has been chosen for illustration and description herein.

Accordingly, one way of achieving the fore If desired, a single blankshaped or suitably cut and bent into the desired form, with the meetingedges joined together in any suitable usual manner.

It will be observed that in the drawings the blocks are shown relativelythin and squarefaced; that the length of the front of the container isshown as approximately twice its width; that this width in turn is shownas slightly greater than the length and width of the block; and that thewidth of the other four walls are shown as slightly greater than twicethe thickness of the blocks. As a result four blocks can be accommodatedwithin the container shown in the drawings, arranged laterally inplification of the practical application of the invention whichcontemplates broadly that the di-- walls be varied to acin size, numberand mensions of the container commodate blocks varied arrangement.

termine by mere impaction the amount of unvaporized material stillremaining within the container.

The end walls 16 and I8 are shown as provided with perforations I?through which the vaporizer permits circulation of air into, through andout of the container and the discharge of vapors therefrom servicedthereby,

and rear walls into the space or closet to be The invention contemplatesfurther that the openings in the side walls It and it be predeterminedas to number, size and location for a particular space in which thedevice is to be employed and that this predetermination be availed of,to control the evaporization of the contents thereof to serve mostefficiently for a particular closet or other type of enclosed space byproviding a group of end walls which are formed separate from thecontainer and whose openings differ as to size or number or location, sothat that particular type of end wall can be selected for the containerwhich can best service a particular closet or similar space. Forexample, the end wall it of Fig. i exemplifies one predetermination ofthese openings, whereas the side wall iii of Fig. exemplifies adifferent predetermination, it being understood that in practice, thegroup may encompass as many different types of predetermmations aspractical considerations require or permit. As a result, the containerill of Fig. 4 can be provided with that selected pair of end walls whichbest meet the requirements of the particular closet or space for whichit is intended.

The means for attaching a pair of end walls to the container shown inthe drawings comprises a pair of opposed guide channels l5 providedalong the long edges of the front and rear walls [0 and H on one end toslidably receive within these channels one of the pair of side wallsselected for use. The long edges on the front and rear walls are formedat the other end with opposed guide channels it in which the second ofthe pair of selected end walls can be slidably received.

When the container is in use, the side wall is in the position shown inFig. 1. It permits the interior of the container to remain visible atall times, as a result of which the user can always determine, by mereinspection, the amount of unvaporized material still remaining withinthe container.

Whenever a refilling becomes necessary or desirable, the side wall itcan be slid edgewise, either part way or into the completely withdrawnposition shown in Fig". 4. This greatly facilitates the refillingoperation, and when it is completed the wall can be restored to itsnormal closed position.

The perforations H in the wall it, and the corresponding perforations inthe opposite side wall l8, permit circulation of air into and out of thecontainer. It will be observed that the air currents necessarilyencounter the blocks of vaporizable material edgewise, and travel alongpaths which are parallel to the larger faces of the blocks. This resultsin more efficient vaporization, i. e., a greater amount of vapor-ladenair is liberated per unit volume of space occupied by the container.Also, the wearing away of the vaporizable blocks is more uniform thanwould otherwise be the case, and this desirable result is especiallytrue where both side walls of the container are provided withperforations.

In order to vary the rate of vaporization of the accommodated blocks,one or both of the side walls can readily be replaced by a side wallsuch as that which is shown at 20 in Fig. 5. It will be noted that thiswall is a similar strip of transparent material, having the sameexternal dimensions as either of the strips it and i8, but beingprovided with perforations 2! which are larger.

If desired, a series of such side walls may .be

provided, each with a different size, shape or arrangement ofperforations, whereby selected walls may be employed, depending upon thenature of the use to which the device is to be put.

The rectangular and relatively flat nature of the container makes itreadily usable in a variety of locations. For example, it may be fittedflatwise against the wall of a closet or the like or into a corner. Forpurposes of suspending the container in a proper upright condition, itis provided with a hook 22 which engages within a pair of apertures 23formed in the top wall l2. The container may also be received into thesleeve or other portion of a garment or the like.

The details herein described and illustrated, except as they areotherwise specifically mentioned in the appended claims, are givenmerely by way of example. For this reason it will be understood thatchanges in these details may be made without necessarily departing fromthe spirit and scope of the invention as expressed in the claims.

Having thus trated its use, what we claim as new to secure by LettersPatent is:

l. A substantially rectangular container for vaporizable material insolid form, comprising relatively wide front and rear walls andrelatively narrow top, bottom and side walls, means engaging the topwall for suspending the container, at least one of said side walls beingcomposed of a strip of transparent material and having perforations topermit air circulation into and out of the container, and channelsformed on the front and rear walls for supporting said side wall inslidable relation so that a refilling opening can be formed by slidingsaid side wall at least partially out of said channels.

2. A substantially rectangular container for vaporizable material in theform of relatively fiat square-shaped blocks, comprising relatively wideunperforated front and rear walls and relatively narrow side walls, andperforations in said side walls to permit air to circulate into and outof the container and to encounter said blocks edgewise, said side wallsbeing composed of strips of transparent material and said front and rearwalls being provided with opposed channels in which said side wallstrips are slidably mounted.

3. A package for dispensing vaporizable ma-, terial comprising acontainer whose width is defined by a pair of relatively wide front andrear walls and whose thickness is defined by a pair of relatively narrowend closure walls one of which is transparent to permit inspection ofthe contents of the container, a plurality of blocks of vaporizablematerial aligned within the container in the direction of one of itssaid dimensions, and openings in an end closure wall. topermit aircirculation into and out of the container, one of the end closure wallsbeing mounted for movement from its normal container closing position toprovide a filling opening through which the container may be refilled.
